Thought maybe Chief 37 or Mike CA could answer this. Andrew's ship, a guided missle frigate, lost one of their two turbines off Central America. They were being told they could not pass through the canal to reach port by the expected Christmas stand down. Now we hear they are flying technicians out to fix it. Any practical reason why they could not pass through the canal. Of course remember Andrew is still doing his first few months of working in the mess, so I realize the Captain is not coming down and consulting Andrew on what to do, you know what I mean.

Thanks, Gene

Your sons ship was named after..... .. third party image

Stephen W. Groves (1917 - 4 June 1942) was born in East Millinocket ME and graduated Schenck High School in 1934. After receiving a mechanical engineering degree from the University of Maine, he joined the Navy in December 1940 and was commissioned in April 1941. Becoming a Naval Aviator he joined USS Hornet in December ‘41. In April 1942 the Hornet transported Lt. Col. James Doolittle‘s Army Air Corps bombers to Japanese waters. This attack set the stage for the Battle of Midway on 4 to 7 June 1942, considered to be one of the most important battles of the war. During that battle Ens. Groves took off nine times and was one of six American planes that fought off a vastly superior Japanese force trying to finish off the Hornet. Ens. Groves never returned from his last flight and was awarded the Navy Cross. USS Stephen W. Groves is named in his honor. (from the USS Stephen W. Groves Website)

GeneMO, I"ve attached a link to an info site about possibly your son"s class of ship. If he"s on a FFG, she has one shaft and two turbines. With one turbine down her capabilities are somewhat degraded and most likely the reason any pilot or Captain would refrain from wanting to negotiate the Canal. Hope they get her repaired and he gets to spend some quality leave time with family over the Holidays.

I was in the Marine Corps instead of the Navy, but I spent a couple of years total aboard ship, aircraft carriers, mostly.

I agree, if it's a civilian pilot who takes a ship through the Canal, it's his call. He (quite understandably) probably doesn't want to take responsiblity for the consequences that could occur while piloting a ship that isn't handling right. And one of the consequences could be blocking the canal to all traffic.

Some of the ships have two turbines driving a single shaft and propeller, some have two shafts and propellers. The issue at hand is redundancy more than manoeverability. Ships are not allowed to transit the canal with a propulsion or steering casualty. With one of the two main engines down, if they were to lose the last remaining engine, they would be dead in the water. With both operational, if you lose one while in transit, you can get yourself to an anchorage for repairs.

Hope this helps.

when ever a ship is in a port or going threw a canal they bring aboard a civilian pilot from the area they are in , i would say he was the one that made the disision.he comands that peticular ship at that time, because thats his job every day.they take him of and on with a tug.

It's pretty hard to maneuver in tight spaces on one prop. It's offset to one side, which means the vessel will respond well to the helm in one direction but not the other. That's what tugs are for, I'd have thought. In reality, a good ship handler should be able to manage it but in the absence of a compelling reason (war emergency) to take the risk, it's probably wise not to take a chance. I hope it works out and you can have him home for Christmas.

Thanks guys, and Yes Jim, I thought of the fact that with two screws it would be hard to steer, but I cant find any information listed on this ship wether or not it has two screws. I know it shows it as having two 50,000 HP gas turbine, but was thinking it just had one screw.

My sailor e mails every day, but we are not supposed to ask or discuss too much technical stuff so I havent ask him.


Thanks again, Gene

It's unlikely to only have one prop, Gene. Almost all Navy ships have at least two... for improved maneuverability as well as redundancy for an engineering casualty or battle damage.

The Perry class Frigates have 2 GE gas turbines (GE LM 2500) 40,000 shp with 1 shaft. It also has 2- 350 hp electric -drive retractible auxiliary propulsion pods for precise maneuvering that also can provide a "come home" capability at 6 knots.

I have a couple of photos of my ship - USS Topeka, going through the canal in 1960. For some reason, I can't post photos on this website any more. ken P.S. The Topeka is now the USS Razor Blades. Cut up for scrap back in the late 70s.

I understand they are scraapping alot of ships.
We wont have much of a reserve fleet left. I was on/in the USS Boston CAG 1 for 3+ years. 1959-1962.
